problem with DVI connection (Samsung 191T and FX5600)

Hi all!
I have a problem with DVI connection on my Computer.
I can use Analog connection without any problem. But DVI connection
never works for me.

Here is what I got.

Intel P4 3.0GHz (HT enabled) w/Vantec VP-C7040
ASUS P4C800-E Deluxe with BIOS Rev.1014 (P4CED14A)
2x Kingston HyperX 512MB DDR PC3200 CAS2 (Dual DDR Mode)
ASUS V9560VS fx5600 128MB with DVI-I and Analog (15PIN) VGA Connection
(ASUS 52.16 Driver and nVidia 52.16 Driver)
Built in Intel 1G NIC, Sound
Sony 16X DVD Rom on Secondary IDE as a Master Drive
Sony 52x CDRW on Primary IDE as a Master Drive
Sony 1.44NB FDD
2x WD 160GB JB (8MB Cache) with Raid 0
Samsung Syncmaster 191T 19" LCD with Dual Input (DVI and Analog) with
the newest driver
Lian Li Aluminum Case with Vantec VAN-400B 400Watt PSU
Intel Chipset Software Installation Utility 5.0.2.1002 Production
Version
Windows XP Pro with SP1a

I've also tried...

MSI Ti4600 128MB
ATI AIW 9700 Pro

My Problem is...

DVI Connection never works for me.
Contacted Samsung Tech Support and I was told it was Defective
Monitor. So I got a replacement from newegg.
Replacement monitor didn't work. Contacted Samsung Tech Support again.
This time, they said it should be the video card.
Tried 3 different video cards with all different drivers. no luck...
Hooked up CRT monitor and connect 191T as a 2nd Monitor, nView cannot
detect lcd monitor.
And monitor goes to stand by mode.
I guess system is not getting any signal from the Samsung 191T LCD.
It works perfectly fine with Analog, but I want DVI connection.
Can anybody tell what the problem is?
Thanks in advance and sorry for my poor English!

Hi,

When you say it "never works" can you be more specific - that is, do you get
a picture at all, even if distorted? Do you get any response during boot up
(before windows loads)? Do you get an on-screen message on the monitor, like
"no signal" or "out of range", or just nothing? Does the monitor power light
change from orange to green at any stage during bootup?

If you get no response at all, even trying different video cards (and a new
monitor), then the signal is not getting through to the screen. Try a
different cable. Is there an "input priority" setting/switch on the monitor
that you may have to set to DVI (read the manual)? You may have to boot into
Analogue to access that, but don't connect both cables simultaneously after
that, or it will go to analogue every time. Also, try booting up in DVI,
then switching the monitor off and back on again a few times to see if you
can get a signal.

There are a lot of problems with DVI, especially compatibility with the
fx5200 chipset. If you still can't get it to work, email Samsung and request
them to recommend a video card that they can guarantee 100% compatibility
with your monitor. That is the only way I got my Mitsubishi DV172 to work
properly.
